Dan Carpenter fb7bcd1722 fs/ntfs3: Fix an NULL dereference bug 
[ Upstream commit b2dd7b953c ]

The issue here is when this is called from ntfs_load_attr_list().  The
"size" comes from le32_to_cpu(attr->res.data_size) so it can't overflow
on a 64bit systems but on 32bit systems the "+ 1023" can overflow and
the result is zero.  This means that the kmalloc will succeed by
returning the ZERO_SIZE_PTR and then the memcpy() will crash with an
Oops on the next line.

Fixes: be71b5cba2 ("fs/ntfs3: Add attrib operations")
